Member Enumeration Documentation

◆ count_type_t


◆ port_type_t


Member Function Documentation

◆ get_bytes_per_packet()

virtual uint32_t uhd::rfnoc::null_block_control::get_bytes_per_packet ( )
pure virtual

Get bytes per packet

◆ get_count()

virtual uint64_t uhd::rfnoc::null_block_control::get_count ( const port_type_t  port_type,
const count_type_t  count_type 
pure virtual

Returns the number of lines that have been consumed on port 0 since the last reset

port_typeThe port for which the counter value should be returned, sink, source, or loop.
count_typeIf we want the packet count, or the line count

◆ get_item_width()

virtual uint32_t uhd::rfnoc::null_block_control::get_item_width ( )
pure virtual

Get item width (ITEM_W)

◆ get_lines_per_packet()

virtual uint32_t uhd::rfnoc::null_block_control::get_lines_per_packet ( )
pure virtual

Get lines per packet (including the header!)

◆ get_nipc()

virtual uint32_t uhd::rfnoc::null_block_control::get_nipc ( )
pure virtual

Get number of items per clock (NIPC)

◆ get_throttle_cycles()

virtual uint32_t uhd::rfnoc::null_block_control::get_throttle_cycles ( )
pure virtual

Get throttle cycles

◆ issue_stream_cmd()

virtual void uhd::rfnoc::null_block_control::issue_stream_cmd ( const uhd::stream_cmd_t stream_cmd)
pure virtual

Start/stop the null source (port 0)

◆ reset_counters()

virtual void uhd::rfnoc::null_block_control::reset_counters ( )
pure virtual

Reset the counters

◆ set_bytes_per_packet()

virtual void uhd::rfnoc::null_block_control::set_bytes_per_packet ( const uint32_t  bpp)
pure virtual

Set bytes per packet

Note: This sets the entire packet size, including header.

◆ set_throttle_cycles()

virtual void uhd::rfnoc::null_block_control::set_throttle_cycles ( const uint32_t  cycs)
pure virtual

Set throttle cycles

The block will wait this many cycles between packets. Useful for reducing the data output.
